Convicted double killer Colin Abbott won’t be getting a trial after all.

A Butler County judge on Friday denied Abbott’s request to back out of his plea deal, asserting that the defendant’s “demeanor and lucidity” during the plea hearings belied his claim that he was under extreme duress.

Further, Judge William Shaffer wrote that even if all of Abbott’s claims were true, they still wouldn’t hit the standard to back out of a plea arrangement after sentencing, called “manifest injustice.”

“That the defendant entered his plea because he was fearful that he would not prevail at trial we have no doubt,” Shaffer wrote in his seven-page opinion. “Such a fear, however, is a perfectly valid reason for entering into a favorable negotiated plea agreement ... That was a choice he made knowingly, intelligently and voluntarily. Having made that choice, there is no manifest injustice in having the defendant live with it.”

Abbott, a 42-year-old landscaper from New Jersey, pleaded no contest to two third-degree murder charges in the shooting deaths of his wealthy father and stepmother in June 2011.

Prosecutors believe Abbott killed Kenneth Abbott, 65, and Celeste Abbott, 55, as part of a plan to erase $2 million in debt to his father and to inherit the couple’s $4 million estate.

Investigators found the couple’s remains burned and scattered on their 25-acre Brady Township estate.
